CdTe photovoltaic technology is one of the most successful of the last 10 years, it is one of the first being brought into production together with amorphous silicon (already in the mid-1990s Solar Cells Inc. in the United States, Antec Solar and BP Solar in Europe were producing 60×120 cm modules) and it is now the largest in production among thin film solar cells. CdTe solar cells stand out for the robustness of the absorber material; its high chemical stability and the large variety of successful preparation methods available are the most important ones for large-area module production. In this chapter we will describe the basics of CdTe-based thin film solar cells, from the properties of the single layers, their fabrication methods, the steps that bring this device to high efficiency, and the latest improvements achieved so far.

Abstract
CdTe photovoltaic technology is one of the most successful of the last 10 years, it is one of the first being brought into production together with amorphous silicon (already in the mid-1990s Solar Cells Inc. in the United States, Antec Solar and BP Solar in Europe were producing 60×120 cm modules) and it is now the largest in production among thin film solar cells. CdTe solar cells stand out for the robustness of the absorber material; its high chemical stability and the large variety of successful preparation methods available are the most important ones for large-area module production. In this chapter we will describe the basics of CdTe-based thin film solar cells, from the properties of the single layers, their fabrication methods, the steps that bring this device to high efficiency, and the latest improvements achieved so far.
